      which does not work.  Removing these attempted privileges makes
      this identical to option 5 so remove it completely.  The spirit
      of the program appears to be aimed at database privileges, so do
      not add another option for granting global privileges as it may
      be unexpected.  Fixes bug#14618 (same as previous patch, this
      time applied to -maint tree).

      Bug#29838 - myisam corruption using concurrent select ... and update · 4158e75d
      unknown authored
      When using concurrent insert with parallel index reads, it could
      happen that reading sessions found keys that pointed to records
      yet to be written to the data file. The result was a report of
      a corrupted table. But it was false alert.
      
      When inserting a record in a table with indexes, the keys are
      inserted into the indexes before the record is written to the data
      file. When the insert happens concurrently to selects, an
      index read can find a key that references the record that is not
      yet written to the data file. To avoid any access to such record,
      the select saves the current end of file position when it starts.
      Since concurrent inserts are always appended at end of the data
      file, the select can easily ignore any concurrently inserted record.
      
      The problem was that the ignore was only done for non-exact key
      searches (partial key or using >, >=, < or <=).
      
      The fix is to ignore concurrently inserted records also for
      exact key searches.
      
      No test case. Concurrent inserts cannot be tested with the test
      suite. Test cases are attached to the bug report.

        Bug#29838 - myisam corruption using concurrent select ... and update
        Fixed mi_rkey() to always ignore records beyond saved eof.

      Bug #29717 INSERT INTO SELECT inserts values even if · 791584ae
      unknown authored
       SELECT statement itself returns empty.
      
      As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
      can return one row instead of an empty result set.
      
      When GROUP BY only has fields of constant tables
      (with a single row), the optimizer deletes the group_list.
      After that we lose the information about whether we had an
      GROUP BY statement. Though it's important
      as SELECT min(x) from empty_table; and
         SELECT min(x) from empty_table GROUP BY y; have to return
      different results - the first query should return one row,
      second - an empty result set.
      So here we add the 'group_optimized_away' flag to remember this case
      when GROUP BY exists in the query and is removed
      by the optimizer, and check this flag in end_send_group()

      Raise the 64 character limit for path names in the error messages · 00d694a9
      unknown authored
      to 150 or 107 characters for those messages which are generated
      by the embedded server during release builds.
      
      This fixes bug#16635:
         Error messages wrong: absolute path names, "%s" format code
      
      See the bug report or the changelog for "sql/share/english/errmsg.txt"
      for instructions how to do that with other languages, 
      even at the customer site, and for the restrictions to keep.
      
      
      sql/share/english/errmsg.txt:
        The embedded server uses absolute path names in its error messages,
        in the release build environment these exceed the 64 character limit
        which the format strings for the error messages impose (bug#16635).
        
        But when the messages are output, the server does the "printf()" 
        internally in a 256 character buffer; the constant text and the
        expanded variables (strings, error number) must fit into this.
        
        (If the buffer would overflow, a format specification will not be
        expanded but just copied with its code, and the message output
        will just contain '%s' or '%d' where a value is expected.)
        
        So the string lengths are increased to 150 characters in those messages
        which are issued by the embedded server during release tests
        and contain 1 (one) path name,
        but only to 107 in the "rename" message which contains 2 (two).
        
        This solves bug#16635 for the release builds.
        
        For other languages used by OEM customers, similar fixes may be needed,
        but we cannot test them.
        
        These fixes can be done even in a binary installation at the customer site
        by following these steps:
           cd <<install-root>>/share
           $EDITOR <<lang>>/errmsg.txt
           ../../bin/comp_err -C./charsets/ <<lang>>/errmsg.txt <<lang>>/errmsg.sys
        and then restarting the server.

      Fixed bug #29911. · 72c6c789
      unknown authored
      This bug manifested itself for join queries with GROUP BY and HAVING clauses
      whose SELECT lists contained DISTINCT. It occurred when the optimizer could
      deduce that the result set would have not more than one row.
      The bug could lead to wrong result sets for queries of this type because
      HAVING conditions were erroneously ignored in some cases in the function
      remove_duplicates.

      Bug#27198: Error returns from time() are ignored · a7e5f73a
      unknown authored
      gettimeofday() can fail and presumably, so can time().
      Keep an eye on it.
      
      Since we have no data on this at all so far, we just
      retry on failure (and log the event), assuming that
      this is just an intermittant failure. This might of
      course hang the threat until we succeed. Once we know
      more about these failures, an appropriate more clever
      scheme may be picked (only try so many times per thread,
      etc., if that fails, return last "good" time() we got or
      some such).  Using sql_print_information() to log as this
      probably only occurs in high load scenarios where the debug-
      trace likely is disabled (or might interfere with testing
      the effect).  No test-case as this is a non-deterministic
      issue.
      
      
      sql/mysql_priv.h:
        Bug#27198: Error returns from time() are ignored
        
        move declarations for log.cc to before inclusion of

        there.

      BUG#27564 - Valgrind: UDF does not cleanup correctly · b7bf9725
      unknown authored
      Dropping an user defined function may cause server crash in
      case this function is still in use by another thread.
      
      The problem was that our hash implementation didn't update
      hash link list properly when hash_update() was called.
      
      
      mysys/hash.c:
        The following requirement wasn't met by hash_update() function
        causing corruption of hash links list:
        
        After a record was unlinked from the old chain during update, it
        holds random position. By the chance this position is equal to
        position for the first element in the new chain. That means
        updated record is the only record in the new chain.

      Fixed bug #29294. · 166d3c91
      unknown authored
      The `SELECT 'r' INTO OUTFILE ... FIELDS ENCLOSED BY 'r' ' statement
      encoded the 'r' string to a 4 byte string of value x'725c7272'
      (sequence of 4 characters: r\rr).
      The LOAD DATA statement decoded this string to a 1 byte string of
      value x'0d' (ASCII Carriage Return character) instead of the original
      'r' character.
      The same error also happened with the FIELDS ENCLOSED BY clause
      followed by special characters: 'n', 't', 'r', 'b', '0', 'Z' and 'N'.
      
      NOTE 1: This is a result of the undocumented feature: the LOAD DATA INFILE
      recognises 2-byte input sequences like \n, \t, \r and \Z in addition
      to documented 2-byte sequences: \0 and \N. This feature should be
      documented (here backspace character is a default ESCAPED BY character,
      in the real-life example it may be any ESCAPED BY character).
      
      NOTE 2, changed behaviour:
      Now the `SELECT INTO OUTFILE' statement with the `FIELDS ENCLOSED BY'
      clause followed by one of: 'n', 't', 'r', 'b', '0', 'Z' or 'N' characters
      encodes this special character itself by doubling it ('r' --> 'rr'),
      not by prepending it with an escape character.
      
      
      sql/sql_class.h:
        Fixed bug #29294.
        The ESCAPE_CHARS macro constant is defined to enumerate
        symbolic names of espace-sequences like  '\n', '\t' etc.
        The select_export::is_ambiguous_field_sep field has been added
        to distinguish special values of the field_sep field from
        another values (see ESCAPE_CHARS).
      sql/sql_class.cc:
        Fixed bug #29294.
        The select_export::send_data method has been modified to
        encode special values of the field_sep field by
        doubling of those values instead of prepending them with a
        value of the escape_char field.
        Example: The SELECT 'r' INTO OUTFILE FIELDS ENCLOSED BY 'r'
        now produces the 'rr' output string instead of x'5c72'
        (i.e. instead of sequence of 2 bytes: \ and r).
      sql/sql_load.cc:
        Fixed bug #29294.

      unknown authored
      Sometimes special 0 ENUM values was ALTERed to normal
      empty string ENUM values.
      
      Special 0 ENUM value has the same string representation
      as normal ENUM value defined as '' (empty string).
      The do_field_string function was used to convert
      ENUM data at an ALTER TABLE request, but this
      function doesn't care about numerical "indices" of
      ENUM values, i.e. do_field_string doesn't distinguish
      a special 0 value from an empty string value.
      
      A new copy function called do_field_enum has been added to
      copy special 0 ENUM values without conversion to an empty
      string.
      
      
      sql/field_conv.cc:
        Fixed bug #29251.
        The Copy_field::get_copy_func method has been modified to
        return a pointer to the do_field_enum function if a conversion
        between two columns of incompatible enum types is required.
        The do_field_enum function has been added for the correct
        conversion of special 0 enum values.
